Girl #1: Doesn't tip housekeeping at hotels. Only tips if she's renting a house and gets housekeeping.And for valets:
Girl #2: $10 a day, which she leaves in an envelope at the front desk. Since she stays at nice resorts, she thinks $10 is customary.
Me: A buck or two a day (regardless of whether it's the Days Inn or Four Seasons), which I leave on the nightstand.
Guy #1: Doesn't tip unless it's a business trip.
Girl #1: Usually a buck.
Girl #2: Several dollars, depending on how much valet costs. If valet costs $15, she might tip $3.
Me: Usually a buck.
Guy #1: Usually a buck or two.
